An HVAC system includes a first air quality sensor and a second air quality sensor. The system contains a controller which calculates a differential between the first air quality sensor and the second air quality sensor. The differential is compared to a threshold. If the threshold is satisfied, a fan is engaged which may, reducing the air quality differential as sensed by the first and second air quality sensor.

System and method for HVAC fan control

A multi-zone environmental control system such as an HVAC and/or an IAQ control system includes a control module, a primary user interface, and at least one secondary user interface. The control module is configured to control an environmental system and controlled devices, each device associated with a respective zone. The primary user interface is in communication with the control mode and associated with a first zone. The primary user interface displays information to the user, receives inputs from the user regarding control of at least the first zone, and transmits signals to the control module, which then controls the device associated with the first zone. Each secondary user interface is associated with a zone other than the first zone and is configured to display information to the user, receive an input from the user concerning control of the respective zone, and communicate with the primary user interface. In turn, the primary user interface transmits signals to the control module, which then controls the devices associated with the respective zones.
